Manifold



FIG. 1 is a front perspective view of a manifold showing our new design;

FIG. 2 is a front elevational view of the manifold of FIG. 1; and,

FIG. 3 is a top plan view of the manifold of FIG. 1.

The rear elevational, side elevational, and bottom plan views are not shown and form no part of the claimed design. The portion shown in broken lines is for illustrative purposes only and forms no part of the claimed design. 

We claim the ornamental design for a manifold, as shown and described.
